My invention relates to the class of burners above mentioned and more especially designed for the burning of oil, and an object of my invention, among others, is the roduction of a burner of this class that s vall be simple in construction and particularly eicien't in operation. A

One form of a burner embodying my invention, and in the construction and useof which the objects herein set out, as well as others, may be attained, is illustrated in the .accompanying drawings in which- Figure 1 is a view in side elevation of my groove 18 may be regulated byjvalves' as improved burner. v

Figure 2 is a similar view, but looking from a point at right angles to the point of view of Figure l, the perforations in the wall of one case being only partially shown in thesefigures.

Figure 3 is a burner.

Figure 4 is a top view of the burner base. Figure 5 is a view in central vertical section through my improved burner.

Figure 6 is a fragmental view showing a slightly different form of the burner. y y Y In the accompanying drawings the numeral 6 indicates a 7 at one end andon adjusting screws 8 at the opposite end, ployed as a means for leveling the device as" a whole. A tubular support 9 rises from the base, and receives a post 10 that is adjustably secured as by means of a screw 11. A burner base 12 is secured to the upper end of the post 10, as by means of screw threaded en agin parts.

aid ase supports two burners, 1n the construction herein shown, both of Ithese burners being of similar construction, and the ,description thereof will therefore be confined to a single burner. A uel groove 13 is formed in the base, extending completely around it, and this-groove is supplied wit fuel through a supply pipe 14, there being two of these supply pipes connected with a l common supply pipe 15 and extending horia drip cup 1 zontally therefrom and then upwardly to the burner, as shown in Fig. 2 of the drawings. Flow oi fuel through'each supply pipe lmay be controlled as by means of a valve 16, and each suppzly pipe may be provided with A vapor groove 18 is top view of my improved' 28 supplied from the rooveLlS.

base concentric vwith the fuel grobve, 'andI ducts 19 extend from the fuel groove-to the vapor groove, there .being four o f these ducts in the construction herein shown, and these ducts open out of the fuel groove ata point above the bottom of said groove so that uelI v will -not iiow from the fuel to the vapor groove, A .result 'of this construction is that vapor 1s formed 1n the oil groove and rises upwardly-therefrom, said vapor also passa .#Z

ing through the ducts 19 into...i the vapor grooves and the latter ltheref're receive?l nothing but vapor. The How of oil to the shown, or otherwise, to 4an-amou'nt substantially not greaterthan the amount consumed es v and vaporized in the groovesv 13 and18,

thereby preventing ow of oil throu h the ducts 19.. Yapor only, therefore, will exist and be ignited in the Combustion chamber By reason of the act that these ooves extend around the burner, it isessential that the level of the oil within vthe grooves 13 shall be the, same at all points in order to prevent such. oil from passing'through' any of the ducts 19 into the vapor groove 18. *.j

Flanges 20f21-22 and 23 are conoentrically :formed on the base, rising therefrom,

extend upwardly there om forming combustion chambers 28-29. An opemn 30 within the case 27 is closed at its top y a cap 31, and the space between thef/shells or cases --26 is closed at the top by a ring .and shells or cases 24-25-`-26 and 27- are .A l

formed to 'fit said flan es, and said shells 32. The .wallso/f the cases 24 and 27 are provided Jwith /erforations 33 throu houtv their entire sur ace, a portion only o drawings herein.

said perforations, however,A being shown in .the

Fig. 6 the burner base 12 has thesupply pipe y This structure is similar to that hereinbefore described, with lthe exception that this fuel groove is wider and deeper with respect to the vapor grpove than is the groove shown in' the device of the preceding figures.

In accordance withthe ,provisions of the patent statutes I have described the princidescribed with respect lto the devicef-f hereinbeforeset forth, and4 it also has a vapor groove 18 with a duct or ducts 19 extending 'y from the vapor groove to a fuel groove 34.' .iv

ples of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim- 1. A burner including a burner base having therein a fuel groove, a vapor grooveI to recelve for ignition therein vapor from said fuel groove, a duct communicating with both of said grooves and located above the bottom of the fuel groove to effect flow of vapor only to the vapor groove under normal operation of the burner, a combustion chamber openingfrom each of said grooves, and means for supplying fuel to the fuel groove.

2. A burner including a burner base haveach of said grooves,

ing therein a circular fuel groove, a coce tric vapor groove to receive vapor from said fuel groove, a duct communicating with and located above the bottom of both of said grooves to effect flow of vapor only to the vapor groove under normal operation of the burner, a combustion chamber opening from and means for supplying fuel to the fuel groove.

3. A burner including a base having therein a vapor groove, a fuel groove deeper and Wider than said vapor groove and surrounded by the latter, a duct communicating with said grooves and located above the bottoms thereof, to conduct vapor only to said vapor groove, a combustion chamber for each of supplying fuel said grooves, and means for to the fuel groove.
